Kansas City-Style Baby Back Ribs

These Kansas City-style baby back ribs are the ultimate treat for fans of authentic, slow-cooked barbecue. Distinctive for their thick, sweet, and tangy tomato-based glaze, these ribs are first treated to a savoury dry rub and then baked until perfectly tender. The addition of molasses and cider vinegar to the homemade sauce creates a complex depth of flavour that far surpasses anything you can find in a bottle, ensuring a sticky, finger-licking finish every time.

Perfect as a dairy-free main course for a casual weekend gathering or a summer garden party, these ribs are best served with classic sides like crunchy coleslaw and corn on the cob. By using the oven for the initial cooking and finishing them under the grill, you can achieve that sought-after charred texture and deep mahogany colour without needing a professional smoker. It is a foolproof way to bring the taste of American barbecue into your home kitchen.

How to make Kansas City-Style Baby Back Ribs

Line a large heavy rimmed baking sheet with foil and put rib racks side by side in pan.

In a bowl, whisk together 50g brown sugar, chilli powder, paprika, salt, pepper, and cayenne and rub onto both sides of racks. Let ribs stand, meaty sides up, at room temperature, 1 hour.

Preheat oven to 325°. Cover pan tightly with foil and bake ribs 1 1/2 hours.

Make sauce while ribs bake: Cook onion in oil in a 3-4-quart heavy pot over medium-low heat, covered, stirring occasionally, until tender, 10-15 minutes. Add garlic and cook, stirring, 1 minute. Add remaining ingredients, including remaining 70g brown sugar, and simmer, uncovered, stirring occasionally, 15 minutes. Cool sauce slightly and purée in a food processor. Set aside 240ml sauce for serving.

Remove foil cover and turn racks over so bone ends curve up, then baste ribs with pan juices and spread generously with some sauce. Continue to bake, uncovered, 30 minutes. Turn racks over, then baste again with pan juices and top generously with more sauce. Continue to bake until tender when pierced with a small knife, 30-45 minutes.

Grill ribs, meaty sides up, 4"-6" inches from heat, until browned, 2-3 minutes. Serve with reserved sauce.
